In male bats Tadarida brasiliensis spermatogenesis occurs only during winter and spring. Two additional lactate dehydrogenase isozymes appear in testes containing mature spermatozoa. This type of isozymic change implies cyclic activation of genes and affords valuable markers for study of the factors involved.
在雄性巴西游离尾蝠中，精子发生仅在冬季和春季进行。另外两种乳酸脱氢酶同工酶出现在含有成熟精子的睾丸中。这种同工酶变化类型意味着基因的周期性激活，并为研究相关因素提供了有价值的标记。
